I maidened my FT22 today that I built from a FT speedbuild kit, but I supplied my own electronics. The good news is that it flew fairly well out of the gate with only minimal trimming (4 clicks down elevator) required to achieve smooth level flight. It flew around at basically level flight cruising around the park for 5.5 minutes on a Turnigy Nano-Tech 1000 mah battery before hitting LVC.
The bad news is that it would barely climb and I had to fly it at WOT the entire time. It would do some very mild aerobatics (IE a single barrel role) but it lost so much altitude that I could never do more than 1 at a time. It would not loop (pitched straight up to about a 80 degree angle and climbed until it stalled). At the end of the flight the motor was very hot (certainly too hot to hold).
I think the CG is just about perfect but I could be wrong (this is my first successful scratch build). If I balance on the indicated CG marks, I get about a 5 degree nose-down attitude. I am guessing I have an issue with my choice of power pack. Right now it has:
The motor honestly looks a little tiny IMO, so my first thought was to replace it with something that has more beef. Or I could potentially swap out the prop? Both? Something else entirely? I have the following on hand for a quick swap out:
Any suggestions are greatly appreciated! I'm hoping to get back out tonight around dusk for another go-round...

- ESC - Turnigy Plush 30A w/ BEC
- Motor - HexTronic 24g 1300KV (HXM2730-1300)
- Prop - 8x4.5
- Battery - Turnigy Nano-Tech 1000mah 3S

- Turnigy D2836/8 1100 KV outrunner
- 8x6 props
- 10x4.5 prop (probably too big for the slot)
Any suggestions are greatly appreciated! I'm hoping to get back out tonight around dusk for another go-round...
